142325-62-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 142325-62-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,3,2 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 142325-62:
(8*1)+(7*4)+(6*2)+(5*3)+(4*2)+(3*5)+(2*6)+(1*2)=100
100 % 10 = 0
So 142325-62-0 is a valid CAS Registry Number.
